He's the CEO and sole shareholder of Landry's, which owns Bubba Gump Shrimp Co., Morton's The Steakhouse, and the Rainforest Café.

The hospitality mogul is also the host of CNBC's "Billion Dollar Buyer," in which he travels the country to meet up-and-coming suppliers and decide if they have what it takes to partner with his empire.

Tilman Fertitta, entrepreneur and host of Billion Dollar Buyer.

Unsurprisingly, Fertitta wakes up to a lot of emails each day, sometimes hundreds. How does he manage them all?

"When I go through 80 to 100 emails every morning, I go back and I flag them," the billionaire tells CNBC. "Then, later in the day, I will go back and ask that person questions, or even call them if I want a real detailed answer and not let them off the hook. Being able to flag and come back and look is just great."

"My morning routine is to get up in the morning, andI truly like to sit there for an hour and drink coffee, go through all my emails, look at all my reports from the night before, give comments, and set up my day that way," Fertitta explains.

Right away, he wants to know "what's going on in the world and who's looking for me today."
